single process

.bar file contains multiple processes from diagram? How do I export a single process within a diagram?

I have a single diagram with multiple processes within it. Using the export function I created .bar files for each process within the diagram.

I send a single .bar file to a collegue and he tried to import this single .bar file. But when he did, he got the full diagram that i made, with all the processes, instead of just the single process associated with the .bar file i gave him.
